Abstract:

Sodium alginate fibers have been extensively studied due to being non-toxic and have high moisture retention, high oxygen permeability, biocompatibility, and biodegradability. However, their application has been limited due to their poor mechanical performance. In this study, poly(ethylene glycol) diglycidyl ether-modified sodium alginate fibers were prepared by spinning the solution after mixed reactions through a spinneret into a coagulation bath containing aqueous CaCl2. The properties of the spinning solution, the structure and physical properties of the modified sodium alginate fibers wit

Abstract:

Injectable biomaterials have attracted more and more interest owing to their advantages over traditional open surgeries: minimal invasive procedure and ease of handling. Commonly used synthetic injectable polymers exhibited low drug loading and poor biodegradability. In this work, we describe a novel series of degradable copolymers comprising salicylic acid–based poly(anhydride-esters) and poly(ethylene glycol) subunits suitable for injectable drug releasing applications. By tuning the rheology properties, these salicylic acid–based poly(anhydride-esters) and poly(ethylene glycol) copolymers m

Thermoresponsive polymers have been widely studied in the past decades due to their potential applications in biomedicine, nanotechnology, and so on. As is known, poly(N-isopropylacrylamide) (PNIPAM) and poly(oligo(ethylene glycol)methacrylates) (POEGMAs) are the most popular thermoresponsive polymers, and have been studied extensively. However, more advanced thermoresponsive polymers with excellent biocompatibility, biodegradability, and bioactivity also need to be developed for biomedical applications.

The hydrogels based on chitosan were prepared by Michael-type addition reaction between chitosan's primary amino groups and maleimide group terminating poly (ethylene glycol) (PEG) under mild conditions. The hydrogels were characterizatied by FTIR, TG, etc. The study on the swelling behavior indicated that the hydrogels possess pH-and thermo-sensitivity. The chitosan-based hydogels crosslinked by Michael-type addition reaction have a potential application on biomaterials due to its biodegradability, biocompatibility, less toxicity and hydrophilicity.

Abstract:

There is a global trend to replace the production of conventional recyclable plastics with biobased ones, allowing a sustainable alternative adapted to the current concept of a circular bioeconomy. Forest-industrial and agricultural biomass wastes (lignocellulosic biomass waste, LCBW) produce severe problems in some developing countries because they are improperly disposed of or burned in the open air. Such wastes are attractive as a raw material to produce bioplastics due to their low cost. Furthermore, low-pollution processes can complete an economical and environmentally friendly approach.

Abstract:

Gelatin, a hydrophilic protein derived from collagen, has been widely used in drug delivery system because of its biocompatibility and biodegradability. However, its high water solubility limited its interaction with hydrophilic drugs. The current works propose a method to improve surface activity of gelatin by modifying it into an amphiphilic molecule via conjugating with cholesterol. High contents of cholesterol were conjugated to amino groups (-NH2) of gelatin using N,N’-Disuccinimidyl carbonate. Cholesterol contents were varied from 100% by mole of free -NH2 group in gelatin.

The hydrogel formed by polyethylene glycol-aliphatic polyester block copolymers is an ideal bioink and biomaterial ink for three-dimensional (3D) bioprinting because of its unique temperature sensitivity, mild gelation process, good biocompatibility, and biodegradability. However, the gel forming mechanism based only on hydrophilic-hydrophobic interaction renders the stability and mechanical strength of the formed hydrogels insufficient, and cannot meet the requirements of extrusion 3D printing.

Abstract:

Poly(L-lactide) (PLLA) is a promising candidate as a bioplastic because of its non-toxicity and biodegradability. However, the low flexibility of PLLA limits its use in many applications. Poly(L-lactide)-b-poly(ethylene glycol)-b-poly(L-lactide) (PLLA-b-PEG-b-PLLA) block copolymer is of interest for bioplastic applications due to its superior flexibility compared to PLLA. The aim of this work is to modify PLLA-b-PEG-b-PLLA using a low-cost calcium carbonate (CaCO3) filler to improve material properties compared to PLLA/CaCO3 composites.

Glioblastoma (GBM) is the most common and deadly primary malignant brain tumor. Current therapies are insufficient, and survival for individuals diagnosed with GBM is limited to a few months.

Polymersomes (PMs) are PNs that have been described as having attractive characteristics, mainly due to their stability, prolonged circulation period, biodegradability, their ability to sustain the release of drugs, and the possibility of surface functionalization.

Poly(lactic acid) (PLA) is currently the most widely used material in 3D printing. PLA has good mechanical properties, chemical stability, and biodegradability, but its surface is hydrophobic and cannot be effectively used. The growth metabolism of attachments, how to increase the strength of PLA with high brittleness, and 3D printing of PLA materials for the biomedical field have always been a topic of research by scientists. This experiment used fused filament fabrication (FFF) to prepare structures. First, the 3D-printed polymer surfaces were treated with an atmospheric-pressure plasma jet

The test results for the mechanical properties showed that the strength of the PLA/PEG alloy decreased with increasing PEG content, leading to an increase in elongation. The differential thermal a

The functionalization of poly(ε-caprolactone) (PCL) with azide group enabled attachment to P(AlHEMA-co-MPEGMA) copolymers via a “click” alkyne-azide reaction. The introduction of PCL as a second side chain type in addition to PEG resulted in heterografted copolymers with modified properties such as biodegradability. “Click” reactions were carried out with efficiencies between 17–70% or 32–50%
